Manifest Analysis and Certification (MAC) is a process that evaluates the quality of manifesting software manufactured by mail service providers. Manifesting is the efficient way to calculate, document, and pay for postage using a permit imprint instead of affixing meter postage or stamps to your parcels. Developed by the Postal Service in cooperation with the mailing industry, MAC provides a set of criteria that determines the accuracy of manifest products. The MAC Certified Developers List contains a quick reference to qualified developers, contact information, and which Postal Service services they offer — from Priority Mail to Parcel Select to international mail.
